Which 338 to build, RUM, Norma or Lapua

Thinking about a new build in 338, this would be my first 338. I would like the option to find factory ammo even though I reload so I am thinking RUM, Lapua, Norma or even Weatherby. I know there are a lot 338 shooter out there so give me your practical experience with each. I like the Norma but thinking components and factory ammo are going to be hard to come by so probably RUM or Lapua.

Thanks

Re: Which 338 to build, RUM, Norma or Lapua

I shoot and reload for the 338/378 Weatherby. I live in Northern Central B.C. Canada. I can not buy tailor mades anywhere except in Calgary or through the mail at 135 bucks a box plus tax, plus hazmat fee. So I roll my own at 90 bucks a box for20 pieces of brass. Your cost in the lower 48 is around 84 bucks a box or so. As for performance I am still breaking in the barrel and load developing. The rifle seems to be shaping up in the accuracy department. My two reloading manuals Barnes, and Hornady show the 338/378 very close in MV to the Lupua and or the 338 RUM. I should think which one to choose would have to be your call. I think if I had it to do over again I might have gone for the 338RUM because of Ammo availibility. this is a hard call.

An animal on the receiving end wouldn't know the difference between them. I've never bought a factory loaded cartridge that I can remember so that isn't one of my considerations.

I shoot a RUM which will do any thing I wish and a long ways out.

If I had to make a choice, I'd go with the Lapua just for the brass!

Re: Which 338 to build, RUM, Norma or Lapua

I don't have the Norma but have the others and several more. Like Roy said, I can tell you from been there and done that any of your choices will kill anything as far as you can hit it. The difference is product availability and cost, how heavy you want your finished rifle, and what velocity you want to achieve for better drops and less wind drift. About a 100 other things also.

Here are the velocities out of a 28-30" barrel over extensive testing with these at my range. The 338-378 Weatherby outperforms the others by about 200 fps and will push the 300 grainers between 3000-3100 fps, 225's between 3400-3500 fps. The lapua is the next fastest by a little over the RUM case primarily because the Lapua brass can be pushed to higher pressures. At the same pressures the Lapua and RUM case are virtually identical and drive the 300 grainers 2750-2850 fps. They push the 225 grain bullets 3200-3300 fps. The norma is a shortenned, improved Lapua but still performs close to these. I laugh at the loading manuals for wby cartridges. They are incredibly underloaded because of liability concerns since custom wby chambers vary so much.

The RUM's typically can be built on a lighter rifle because they utilize a standard magnum action which is a little lighter. Remington brass is way cheaper. 338-378 brass is over $60 a box now at Graff's. Lapua brass is also expensive. If you are building a rifle Jamison now makes 338 Excalibur brass carried by Midway and Graff's. The 338 Excalibur has the most powder capacity and is the fastest of any easily available over the counter 338 that will fit in a hunting weight rifle. That is what I would build now if I was doing one. For a light 338 carry rifle I would talk to Devin about the 338 SIN he has been working on. Mine weighs 6 3/8 pounds and a light load through it shot over 2700 fps with the 300 SMK. I am going to run the 225 CE bullets through it because of recoil in the light rifle. It is an improved 330 Dakota.

If I was doing an off the shelf rifle in big 338 it would be a remington 700 338 RUM or a Weatherby Accumark 338-378 Weatherby. I have not shot the Savage 338 Lapua. The lapua rifles I have seen in the past are way to expensive for an off the shelf rifle so I would go custom instead of buying one of those. The accumark I would get used like new for $1100-$1300 range. I would not spend the money for a new one when I can get a 338 RUM for a good price that will kill anything.

Re: Which 338 to build, RUM, Norma or Lapua

Thanks, my rifles are working rifles that I carry try to stay in the 10-11 lb range. I am leaning towards the 338 Wby as I have had great luck with Wby calibers and can build from a Remington or another custom action. I like the Weatherby action but they are heavy.

Re: Which 338 to build, RUM, Norma or Lapua

My personal favorite go to rifle in big 338 is my 338-378 wby. I own most and shoot them all and they all shoot good but every time I get serious for a big trophy, "Speed Kills". Accuracy loads in mine with the 300 grainers run 3060-3070 fps and 3466 fps with the 225 CE bullet. The 338-378 Weatherby is an extremely accurate chambering and has been the standard everything else has shot at since the 70's. Still very few that can match it. The improved 338-416 and Excalibur or improved 338-378 are about it at the high end.

I would not build a .338-.378 on a Remington action. I think that there are very few smiths, if any that would build one. There is simply not enough meat for that class of cartridge.
I would probably build a .338 RUM on a remington, unless you have the $$$ then go for a full custom NORMA. The .338-.378 Wby. is awsome, I just think that the cost of ammo is rediculous.
